One tip, save the WD40 for things that get wet and need to be dried. It
is a great water displacement fluid, but it totally sucks as a
penetrating fluid.

Get something like PB Blaster or liquid wrench. They will do in an hour
what WD40 takes 3 days to loosen up.

Hey M,
Glad to see another Jeeper who resides in SPI! I'm in Brownsville.
Have you done the 30 mile dune ride north of the Island?

Hey M,

Have you done the 30 mile dune ride north of the Island?

 

Oh that's a big 10-4 on the 30 mile run up to the cut. I did that first
thing after I got the jeep over here on the ferry while the bridge was out.
I need to get some wider tires and rims at some point but I've gotten pretty
good at staying un-stuck. Wish the topside of the jeep was in as good shape
as the underside is. Slopped some Napasco on the driveshaft and might need
some in a couple of other spots underneath but looks like it will outlast
the topside. Leaf springs need it too but they did a good job of rubberizing
most of the underside at the factory. Hey do you know a good body shop
around here?

Great to see the sunshine this week after that danged overcast crap, eh?

as the underside is. Slopped some Napasco on the driveshaft and might need
some in a couple of other spots underneath but looks like it will outlast
the topside. Leaf springs need it too but they did a good job of rubberizing
most of the underside at the factory. Hey do you know a good body shop
around here?

Great to see the sunshine this week after that danged overcast crap, eh?

Thanks for the tips Mike!! I've never used these other products but yep
they'd be worth using I'm sure. Have a preference for PB Blaster or Liquid
Wrench? Have a really great little ACE hardware here that I bet has both.

Also, if you've never tried TriFlow teflon lube it's a great product too. I
use it on my bicycle chains and it doesn't grab as much dirt as WD-40 does
and it's really slippery stuff- you can feel a big difference in pedaling
effort. Having to learn about these specialized lubes and such since I'm now
in salt air/sand blast all the time. Never needed anything except WD-40
before heh.
